Chaturanga the original game, Chess was its variant

Chaturanga, a strategy game originating in India at least 1,500 years ago, is considered the forerunner of modern chess. Each player commands an army with four different military units: infantry, elephants, cavalry, and chariots.
Chaturanga is the original game of India and chess is a variant developed from it, representing an evolution through transformations carried out by Arabs and Europeans. Yes friends, Chess is a variant of Chaturanga
The objective is to capture the enemy king through strategic moves and tactics. Winning the game implies capturing all the opponent's pieces and leaving his king unprotected.
